Steering wheel shimmy at highway speeds

[SAM LETZRING]

I recently had this problem with 86 4KCSQ- turned out to be one shot a-arm
bushing on rear- replaced with Delrin bushings- very smooth now all the way
to >> 80mph

Also had this same problem 10 yrs ago on front- Delrin fixed that too

Delrin gives a harsher ride- but much better (IMHO) stability.
